An approach is termed non-precision because it provides what type of guidance?

The term "non-precision approach" refers to a type of approach procedure that provides lateral course guidance but does not offer vertical guidance for an aircraft during its descent to the runway. This means that pilots receive information primarily on the horizontal path they need to follow to align with the runway, often through navigational aids such as VOR (VHF Omni-Directional Range) or NDB (Non-Directional Beacon).

In contrast, precision approaches, like the Instrument Landing System (ILS), provide both horizontal (lateral) and vertical guidance, allowing pilots to follow a specific glide path down to the runway. Other choices involve types of guidance that do not pertain specifically to the definition of a non-precision approach, making it clear that the main characteristic of non-precision approaches is their focus on lateral course alignment without vertical assistance.
